Fractures de Tillaux de l’adolescent

[Ankle fractures in children and adolescents]

In children and adolescents, injuries of the ankle are seen frequently in routine practice. The fracture pattern is less dependent on the mechanism of injury than on the maturity of the growth plate. Therefore, a differentiation is made between fractures with open epiphyses and fractures with a closing growth plate in adolescents. The potential for growth-related spontaneous deformity correction is limited, so axial alignment especially in the frontal plane has to be achieved during initial treatment. In displaced articular fractures an anatomical reconstruction of the articular surface and stable osteosynthesis have to be achieved to minimize the risk of early osteoarthritis. Growth arrest is not always avoidable despite an ideal reconstruction and can occur in all fracture types; however, with optimal conservative or surgical treatment, iatrogenic damage of the epiphysis can be avoided thereby reducing the incidence of growth disorders as a complication of ankle fractures in children and growing adolescents.

[Salter-Harris type IV epipyseal fracture of the lateral malleolus. A rare injury in childhood]

This is a case presentation of a 9-year-old boy who sustained a rare Salter-Harris type IV distal fibular fracture including an avulsion fracture of the anterior inferior tibiofibular ligament at the fibular attachment. Treatment consisted of open reduction and internal fixation by Kirschner wire and cerclage. Possible posttraumatic growth disturbances and the major implications are highlighted.
